Summary Box: Google CEO grilled in Oracle trial

THE WITNESS: Google CEO Larry Page spent nearly an hour in a federal courtroom Wednesday, called as Oracle's witness in its legal dispute with Google.

THE ADVERSARY: He was grilled by David Boies, a tenacious lawyer who made headlines for grilling former Microsoft Corp. CEO Bill Gates in an antitrust lawsuit filed by the U.S. government in 1990s. Boies is working for Oracle in this trial.

PERFORMANCE: The taciturn Page often looked uncomfortable. He frequently said he couldn't remember seeing some of the internal Google documents that Oracle is using to build its case.
